At present, current air conditioner product is under the lower condition of outdoor environment temperature, air conditioning system heats the volume not enough, it is relatively poor to heat the travelling comfort, for promoting air conditioning system's heating volume, adopt the mode that promotes compressor operating frequency to increase the heating volume usually, this mode can promote the heating volume to a certain extent, but also can aggravate the frosting condition of air condensing units condenser, make the quick decay of the heating volume of system, frequently get into the defrosting, lead to indoor temperature fluctuation, influence the travelling comfort effect.
Disclosure of Invention
The invention solves the problem that when the heating capacity is increased by adopting a mode of increasing the running frequency of a compressor in the prior art, the frosting condition of a condenser of an outdoor unit of an air conditioner is aggravated, so that the heating capacity of a system is quickly attenuated, and the defrosting is frequently carried out, so that the indoor temperature is fluctuated, and the comfort effect is influenced.
In order to solve the above problems, the present invention provides a control method for delaying frosting, comprising the following steps:
s100, acquiring an ambient temperature parameter and an operation parameter of a compressor in an air-conditioning heating mode; the environment temperature parameters comprise outdoor environment temperature and indoor environment temperature, and the operation parameters comprise operation frequency and heating accumulated operation time;
and S200, when the environment temperature parameter and the operation parameter simultaneously meet the entry condition of starting the delay frosting control, controlling the air conditioner to enter the delay frosting control process.
Therefore, after the air conditioner is operated for a period of time, the indoor environment temperature can rise to a certain temperature, the environment temperature parameter and the operation parameter of the compressor are detected in real time and judged according to the detected data, when the entry condition of starting the frosting delay control is met, the air conditioner automatically enters the frosting delay control process, the frosting condition of a condenser of the air conditioner outdoor unit is delayed, the heating operation period of the air conditioner is prolonged, the defrosting times of the air conditioner outdoor unit are reduced, the fluctuation of the indoor temperature caused by the defrosting of the air conditioner outdoor unit is also reduced, and the comfort experience of a user in use is improved under the heating mode; moreover, the control method for delaying frosting in the embodiment can be used on a variable frequency air conditioner product, can also be used on a fixed frequency air conditioner product, and has a wide application range.
Optionally, the entry condition comprises a first entry condition and a second entry condition;
the first entry condition includes: the outdoor environment temperature is less than or equal to a preset outer ring temperature, and the indoor environment temperature is greater than or equal to a first preset inner ring temperature;
the second entry condition includes: the operation frequency is less than or equal to the highest frequency corresponding to the outdoor environment temperature, and the heating accumulated operation time is greater than or equal to a first preset time.
Therefore, when the first entering condition and the second entering condition are simultaneously met, the air conditioner can automatically enter the frosting delay control process, if the first entering condition and the second entering condition are not simultaneously met, the air conditioner continues to normally operate and does not enter the frosting delay control process, and therefore the reliability of the frosting delay control process is guaranteed.
Optionally, the delay frost control process includes:
